I have heard of the NKP making single door cars out of double door
cars by securing the auxiliary doors shut, as below. It occurred to
me "Now, why would they do that?" All the aux. doors can't be
failing... Perhaps during a major shopping a fleet of DD cars could
have new, single doors installed (particularly if wood doors were
replaced with corrugated steel doors, for example.) But, I can't
figure out why they would seal a door shut, reducing the versatility
of the car. The cars had already been rebuilt with steel sides and doors.

had > inverse 4-panel Hutchins ends, the 1924 cars had 5-5-6 inverse
corrugated ends. In the early 1930s, delivery of steel auto carsauxiliary doors either secured shot or removed entirely, making them
single door cars.
